Abstract

For a light beam focused through a biaxial crystal along one of its optical axes, the effect of internal conical refraction in the crystal leads to the formation in the focal image plane of two bright rings separated by a dark ring. It is shown that, with circularly polarized Laguerre–Gauss ${\mathrm{LG}}_0^{\ell }$ beams entering the crystal, this classical double-ring pattern is transformed into a multiring one consisting of $\ell +2$ bright rings.
